In as found condition. Only cleaned the dust from it. Please review photos carefully and feel free to ask any questions. I’ve taken the liberty of listing some examples of what I’ve found in the photo links as well. Here are some words a collectors website has to say about it. In addition to phenic acid it was discovered that the vapors of formic aldehyde (formalin) also had a strong antiseptic power however these gases were toxic by inhalation; devices like the one presented below were built for the sterilization of the operating rooms: at regular intervals the rooms were hermetically closed for 12- 24 hours, the appliances were turned on and the environment was saturated with formalin vapors. Large apparatus for the disinfection of operating rooms or large rooms of the company Aesculap Schering, for its shape and height (45 cm) had been nicknamed “the lighthouse”. It is composed of a metal base on which a 7-burner alcohol lamp rests, then follows a truncated-conical structure that supports a black wooden cylinder crossed from side to side by numerous holes. The formalin tablets were probably distributed over the holes and sublimated by the effect of the underlying heat. It is a fairly rare device, its construction should date back to the late 1800s.
